Try to make it around your clock in less than a minute, if you can do it, you're a real a 'commando.' Joseph Pilates called this exercise the Clock, or as he referred to it on a brochure that sold for $1, "The Commando Exercise, Around the Clock and Back in Less Than a Minute." It's the most important exercise in Pilates, the Double Leg Stretch, done around a clock. On it's own, it's about the quickest, most effective core workout you can do, you can also use it as a fun addition to any mat class, to finish a workout with, or to wake yourself up!
